Unions representing construction workers at Hinkley Point C say they are now hopeful a row over bonus pay can be resolved without strikes after fresh talks were promised by contractors.

GMB and Unite said the discussions were tabled following a “positive intervention” from the plants’ developer EDF.

The unions conducted a consultative ballot last week on whether to accept the bonus pay offered by the BYLOR consortium formed by the companies Laing O’Rourke and Bouygues TP.

"Our members gave this derisory bonus offer the short shrift it deserved by overwhelmingly voting it down,” said GMB national officer for construction Phil Whitehurst.

"If the companies want to avoid strike action, they need to make us a serious offer, which matches our members' skills level, when we get back round the table.

Unite acting national officer for construction Jerry Swain added: “In the face of a looming industrial dispute the client has shown good sense and has stepped in to try to resolve the problem.

“It is hoped that when fresh negotiations commence BYLOR and in particular Laing O’Rourke are prepared to enter into practical discussions and a sensible bonus which meets the expectations of the workforce and ensures the project is delivered on time, can be agreed.”

Laing O’Rourke, the leading partner in the BYLOR consortium, has been asked for a comment but has not yet provided one.
